Guhring 9024640075400 Carbide Jobber Drill 19/64 in

Product Description

The GUHRING 9024640075400 is a solid carbide jobber-length drill bit designed for precision hole-making in non-ferrous and aluminum workpiece materials. Built to DIN specification under Series 2464, it features a FIREX coating that improves wear resistance and extends tool life in demanding production environments. The bit carries a 118-degree faceted point angle with web thinning for reduced thrust at entry, and a regular spiral flute geometry that promotes efficient chip evacuation. At 4.61 inches overall length with a 2.95-inch flute, this drill fits standard jobber-length holders and drill chucks used in CNC and manual drilling operations. The straight-cylindrical shank measures 7.54 mm in diameter, providing secure tool grip without adapter sleeves.

This drill bit is suited for production and maintenance drilling in aluminum and other non-ferrous materials across light manufacturing, aerospace component work, and general machining applications. The 19/64-inch diameter (0.2969 inches decimal) with a 5xD flute-to-diameter ratio supports stable drilling up to a maximum depth of 2.507 inches (63.69 mm). The two-flute spiral design keeps chip flow clean on through-hole and blind-hole work. No coolant-through capability means it is intended for external coolant or dry drilling setups. This is a tool primarily installed and operated by machinists, toolroom technicians, and maintenance mechanics.

Key Features

• Solid carbide construction, Material Grade K40, for high rigidity and wear resistance
• FIREX coating reduces friction and extends tool life in non-ferrous materials
• 118-degree faceted point with web thinning lowers entry thrust and improves centering
• Regular spiral two-flute geometry promotes reliable chip evacuation
• Straight-cylindrical shank (7.54 mm) fits standard drill chucks without adapters
• Built to DIN specification, Series 2464, for consistent dimensional accuracy

Compatibility

Designed as an OEM-style jobber-length drill bit suitable for standard drill chucks and CNC toolholders accepting a straight-cylindrical shank. Primary workpiece material designation is N (non-ferrous), with aluminum listed as the primary target material. Diameter tolerance is -0.012 to 0.000 mm per DIN specification.

Installation Notes

Installation and operation should be performed by qualified machinists or toolroom technicians familiar with carbide tooling. Ensure the spindle and workpiece are fully secured and the machine is at a complete stop before loading or removing the bit. Carbide tooling is brittle and should not be subjected to side loading, interrupted cuts beyond its rated capacity, or impact during handling. Verify chuck or collet grip on the full shank engagement length before initiating a cut.
